> ------------------------------------
>
> Key: ODE-920
> URL: https://issues.apache.org/jira/browse/ODE-920
> Project: ODE
> Issue Type: Bug
> Components: Axis2 Integration
> Affects Versions: 1.3.5
> Environment: Tomcat/5.5
> Reporter: Felix Neumann
> Priority: Minor
> Labels: axis2, debug, exception, quick_to_fix, solution_known
> Original Estimate: 10m
> Remaining Estimate: 10m
>
> Assumptions:
> * Debug logging is enabled for log4j.category.org.apache.ode.axis2
> * A SOAP request with an empty body is sent to the ODE
> Problem:
> * An error occurs due to trying to access the empty body.
> Reason:
> * The debug output tries to convert that body element to text ("stringify"
> it).
> * Code Reference: Class org.apache.ode.axis2.ODEService, Line 122
> * Code Excerpt: >>>>>__log.debug("Message content: " +
> DOMUtils.domToString(odeRequest.getMessage()));<<<<<
> Solution:
> * Check for an empty body.
> Logged Exception: >>>>>>>>
> 16:40:13,804 ERROR [ODEService] Exception occured while invoking ODE
> java.lang.IllegalArgumentException: Cannot stringify null Node!
